Purpose The purpose of this pilot study was to evaluate tear inflow in a scleral lens system
using fluorophotometry, and indirectly assess the exchange of the tear reservoir in habitual
scleral lens wearers with the presence or absence of midday fogging (MDF). Methods
Habitual scleral lens wearers (n= 23) and normal scleral lens neophytes (n= 10) were
recruited. Of the 23 habitual wearers, 11 of them experienced MDF and 12 did not have a
diagnosis of MDF. Contact lens-fitting characteristics were evaluated using ocular …
